摘要

研究了含废玻璃粉替代水泥的不同混凝土配合比,并与对照配合比进行了比较。废玻璃粉作为水泥重量的替代百分比(10%、15%、20%和25%)。实验室程序包括54个立方体(100×100×100mm),用于测试混凝土试件在28、56和90天的抗压强度,9个圆柱体(300×100mm)用于测试混凝土在28天的应力-应变。所有含废玻璃粉的试样均表现出较好的强度和良好的性能。从试验结果来看,在28、56和90 d时,添加15% WGP的效果最好。从应力应变关系和相同载荷下,含有玻璃粉的试样应变较小,这意味着其脆性更强

Effect of Glass Powder as Partial Replacement of Cement on Concrete Strength and Stress-Strain Relationship
This research involves the study of different concrete mixes contained waste glass powder as cement replacement, then it was compared to control mixes. Waste glass powder was used as replacement percentages of cement weight (10, 15, 20 and 25%). The laboratory program consisted of fifty-four cubes have 100×100×100mm to test the compressive strength of concrete specimens at 28, 56 and 90 days, and nine cylinders have dimensions (300×100mm) to test stress-stain of concrete at 28 days. All specimens that contained waste glass powder showed good strength compared with reference mixes besides satisfactory performance. From experimental results, the use of 15% WGP is best level among other percentages at 28, 56 and 90 days. From stress – strain relationships and for the same load the strain is less for specimens contain glass powder, which mean a more brittle behavior
